摘要：

The surface tension of six alternative refrigerants, i.e., HFC-32 (CH2F2), HCFC-124 (CHCIFCF3), HFC-125 (CHF2CF3), HCFC-141b (CH(3)CC1(2)F), HCFC-142b (CH3CCIF2), and HFC-152a (CH3CHF2), has been measured in the present study. The measurements were conducted under equilibrium conditions between the liquid and its saturated vapor. The differential capillary-rise method (DCRM) used two glass capillaries, with inner radii of 0.3034 +/- 0.0002 and 0.5717 +/- 0.0002 mm, respectively. Temperatures in the range from 270 to 340 K were considered. The accuracy of surface tension measurements is estimated to be within +/- 0.2 mN . m(-1). The temperatures are accurate to within +/- 20 mK. The temperature dependence of the resultant data were successfully represented by van der Waals' correlations to within +/- 0.1 mN . m(-1) for each substance. Available surface tension data are compared with the present data.
